where we have chosen the subscript IQP to indicate that this is an integer quadratic program, i.e., a minimization of a quadratic function over an integer domain.
As mentioned above and for simplicity, we are using the standard approximation that all peaks in the GKP state have equal weight [1]}.
However, one could also include an envelope that weights peaks differently, in which case this information could also be included in the calculation of the responsibility. In general, integer quadratic programs are NP-hard [2]}, [3]}, so we will require a heuristic strategy that is computationally tractable.
Our approach for a generalized version of alg:translatoreg is summarized in alg:translator, with the case of more complicated configurations of \(p\) -squeezed states left to future study.
